Alot of the same parts for Gbodys, but I think I tried to do a 79 core on an 87 El camino once, and of course it didnt work due to the one headlight:redface:
The ElCamino support is different. As far as 81 and newer go there are two basic core supports. A coupe and a sedan. Since the ElCamino is based on a Malibu wagon,more or less it uses the sedan support. The big difference is in the upper tie bar part of the support.
